     I'm trying to implement AN11085 (speex vocoder) applicaiton on my custom LPC1768 board with the attached UDA1380 board.

     My problem is that I cannot record or play because I cannot configure some of the registers of UDA1380 via I2C. I can just configure the register addresses; 00H, 01H, 02H, 03H and 04H. I can read and write those registers. But, for example, I can not write 22H register address to ajdust the microphone as an input.

     What could be my problem ? Anybody can help me ?
